1、The interference between the tooth tip and the chain is reduced to a low level, and the noise and friction are greatly reduced, bringing a comfortable change speed experience. 2、Corresponding guide Angle design, symmetrical guide Angle of chain outer plate, guide chain and toothed disc & flywheel are more harmonious and smooth when the chain moves up and down, making speed change response more quick and agile. 3、High and small shaft embedded force: Parallel riveting processing technology will be closely linked to become a more durable connection mode, so that the chain at high speed and rapid gear shift can withstand mechanical stampede destruction. 4、High steel, high wear resistance: provide high efficiency of the pedal transmission and stable energy transmission, so that riders win at the starting point, and continue to maintain a high transmission rate. 5、Lightweight, mud hole design: the design of the internal and external chain plate hollow structure, under the condition of unchanged strength, reduce the overall weight. It's a great choice for a lightweight ride or a long ride. 6、High system compatibility: widely used in most road and mountain bike transmission systems on the market.
